Current Sensor Settings
Be sure to read “Handling Cords and Cables” (p. 8).
Connect the optional current sensor to the current input terminal of this instrument.
• To make it easier to identify channels, color-code the cords with colored spiral tubes.
See“Color coding of current sensor (for channel identication)” (p. 36).
• Secure the cords together with a spiral tube if necessary.
See“Bundling the voltage cords and current sensors (If required)” (p. 37).
• Refer to the instruction manual supplied with the current sensor for specication details and
usage procedures.
When measuring power lines that use multiple channels
Use a current sensor of the same model.
Example: Use current sensors of the same model from CH1 to CH3 for the 3-phase 4-wire system.
